CYLINDER-PISTON SEALING APPARATUS Russian patent published in 2017 - IPC F16J15/16 

FIELD: machine engineering.

SUBSTANCE: sealing device comprises a cylinder, at least two disks, mounted in a cylinder on a guide sleeve fixed on one of the sealing surfaces of the quick-lock, spring elements arranged between the discs. Each disk is provided with sealing elements for fixed and mobile connections. The sleeve is provided with the abutments, with one disc is stationary and the other is mounted for axial movement between the stops. The resilient element is capable of cooperating with one of the stops and the disc. Fixed disk from the rear side of the device, opposite to the sealing element rolling compound, is provided a labyrinth sealing ring to form an annular cavity between the sealing element and the ring, the gasket stationary disc surface an annular groove communicating with the annular cavity, and the disk is formed at least one channel, having the ability to communicate the annular space with the source of washing liquid.
